System and method for cleansing addresses for electronic messages

ABSTRACT

A method and system for forwarding an e-mail message intended to be delivered to a first e-mail address to a second e-mail address in the event the first e-mail address is disfavored. An e-mail message is sent from a from a first computer that was originally addressed to a first e-mail address to a second computer that is capable of forwarding the e-mail message to a second e-mail address. The second computer receives the e-mail message and parses the first e-mail address from the e-mail message to determine if there is a second e-mail address associated with the first e-mail address. If there is a second e-mail address associated with the first e-mail address, the second computer sends the e-mail message to a third computer associated with the second e-mail address. If there is not, then the second computer determines if it can suggest a username, or a new sername format to be used for the username associated with the domain name address of the disfavored e-mail address.

FIELD OF THE INVENTION

[0001] The present invention relates to a system and method forforwarding electronic messages, and more particularly, relates tocleansing the addresses for e-mail messages that were previouslyreturned to the sender as undeliverable.

BACKGROUND OF THE INVENTION

[0002] Recent advances in telecommunications networks have drasticallyaltered the manner in which people interact and conduct business. Theseadvances promote efficiency and convenience in one's ability to receiveimportant information. With this in mind, individuals and businessestoday find that their physical and electronic addresses are changingfaster than ever with increased mobility and competing message deliveryservices. Deregulation and privatization of the global postal systems,competing package delivery services, and rapid growth of multiplecompeting electronic mail (e-mail) systems are creating an environmentin which there is no single point of contact for address correction asthere was when the sole messaging provider was the national postalservice.

[0003] Users who enjoy the benefit of sending and receiving e-mailmessages typically subscribe to an Internet Service Provider (ISP)offering such e-mail capabilities (e.g., America Online (AOL), Netcom,and Redconnect) and/or may subscribe to an internet based e-mail service(e.g., juno, rocketmail, yahoo) which each is associated with aparticular e-mail address. Thus, the e-mail address is unique to thee-mail service provider. The uniqueness of an address to a selectedprovider is often apparent on the face of the address, e.g.,DQuine@gaol.com, Quine@juno.com or DouglasQuine@yahoo.com. A user orsubscriber to a particular e-mail service may from time to time desireor need to change service providers (e.g., from DQuine@aol.com toQuineDo@pb.com). Exemplary motivation for these changes may derive fromthe fact that an alternative service provider charges lower rates, orthe existing provider's inability to upgrade its service.

[0004] A user who desires to change from one e-mail service provider toanother suddenly faces the reality of being bound to the old serviceprovider because the user's address is unique to that one provider. Asudden and complete changeover is in many circumstances impossiblebecause the community of people who wish to send electronic messages tothe user are only aware that the old address exists. For example, ane-mail address may be published in an industry directory that is onlypublished once every year or two years. Alternatively, the e-mailaddress may be printed on a business card which cannot be retracted andcorrected. Thus, the user incurs a potentially significant loss ofprospective business by abandoning the old address.

[0005] Currently, there is no effective means in place for addresscorrection of e-mail addresses. Even if the e-mail sender is highlydiligent, there are no resources or processes available to identifycorrected electronic address information. The problem is furtheraccentuated by the fact that extreme competition in internet serviceproviders, and likewise e-mail service providers, results in extremelyhigh obsolesce of e-mail addresses with no means for e-mail forwarding(e.g., closing an AOL e-mail account provides no option for forwardinge-mail intended for that account to a new e-mail address).

[0006] Further, today's web savvy users may have multiple e-mailaddresses which periodically change as new features develop or are lost.Entire domain names can be lost (e.g., lostdomain.com) and all maildirected there may be lost as well. In either case, typically the MAILDAEMON message is returned to the sender, notifying the sender that thee-mail address cannot be found and e-mail message is being returned tothe sender.

[0007] Some service providers offer their user-subscribers the option ofa message forwarding service. These forwarding services operate byreceiving the incoming message, retrieving the portion of the incomingmessage that identifies a selected user who subscribes to the forwardingservice, associating the selected user with a forwarding address throughthe use of a lookup table, and transmitting the message to theforwarding address. The forwarding services differ from the normalmessage delivery service that the central service provider offersbecause a portion of the forwarding address belongs to another centralservice provider. Thus, the forwarded message is actually delivered toits intended recipient by the other or second service provider, i.e.,the forwarded message passes through two central service providers, asopposed to just one provider. The intended message recipient is free tochange the second provider with regularity provided that the recipientalways informs the forwarding service of each change in the secondprovider. However, this message forwarding system only works with viablee-mail address, that is, the e-mail address associated with the firstservice provider must still be active and not obsolete. In fact, fewe-mail services offer forwarding services and few, if any, offer toforward e-mail after the account is closed. Otherwise, the first serviceprovider is only enabled to send the later mentioned MAIL DAEMON messageback to the original sender of the -e-mail message.

SUMMARY OF THE INVENTION

[0008] Accordingly, the present invention relates to a method and systemfor forwarding an e-mail message intended to be delivered to a firste-mail address to a second e-mail address in the event the first e-mailaddress is disfavored. An e-mail forwarding computer is located at athird e-mail address that is programmable to associate disfavored e-mailaddresses with forwarding e-mail addresses.

[0009] In use, a user at a first computer sends an e-mail message to afirst e-mail address at a second remote computer. When this e-mailmessage is returned to the user at the first computer, the user resendsthe e-mail that was originally addressed to a first e-mail address to asecond e-mail forwarding computer that is capable of forwarding thee-mail message to a second e-mail address. The second computer receivesthe e-mail message and parses the first e-mail address from the e-mailmessage to determine if there is a second e-mail address associated withthe first e-mail address. If there is a second e-mail address associatedwith the first e-mail address, the second computer sends the e-mailmessage to a third computer associated with the second e-mail address.

[0010] If there is not a second e-mail address associated with the firste-mail address then the domain name of the first e-mail address isparsed therefrom to determine if the domain address of the e-mailaddress has been registered with the second computer. If yes, then acleansed or suggested new format for the once undeliverable e-mailmessage may be sent to the user of the first computer.

[0011] Thus, an advantage of the present invention is that there is nocooperation needed by the e-mail server associated with the disfavorede-mail address. That is, if an e-mail address becomes disfavored (it isno longer an active e-mail address) either because the associated e-mailserver ceases to exist, or the e-mail account has been left abandonedfor a host of reasons, the present invention e-mail forwarding systemnevertheless operates because no cooperation is needed from the latere-mail server. An additional benefit is that when an e-mail message isforwarded by the present invention, the privacy of the recipient isprotected because the sender of the e-mail message is preferably notnotified of the recipient's forwarding address.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019]FIG. 1 schematically depicts a conventional INTERNETtelecommunications system 10. The FIG. 1 system is exemplary in nature.The present invention can be implemented as program control features onsubstantially all telecommunications service provider systems, andsystem 10 is intended to represent any operable telecommunicationssystem that is used by any telecommunications service provider inconducting communication operations (e.g., facsimile, pager, mobilephone and PDA computers).

[0020] It is to be appreciated that the term “INTERNET” is well known inthe art as designating a specific global international computer networkthat operates according to the TCP-IP protocol. A portion of theINTERNET receives or has in the past received funding from variousUnited States governmental agencies including ARPA, NSF, NASA, and DOE.INTERNET communications protocols are promulgated by the InternetEngineering Task Force, according to standards that are currently setforth in RFC 1602.

[0021] Telecommunications system 10 includes a plurality of user orsignal origination sites 12, 14 and 16, with each site being depicted inreference to a PC capable of generating and transmitting e-mailmessages, wherein each site 12, 14 and 16 corresponds to a specifictelecommunications address. A user may utilize one site or a pluralityof sites. A single city or local service area may have millions of thesesignal origination sites. Each site 12, 14 and 16 corresponds to atelecommunication address that belongs to an individual, business, andother entity having need to avail themselves of telecommunicationsservices.

[0022] It is to be understood that preferably each origination site 12,14 and 16 feeds its signal (addressed to a subscriber identified at aselected service provider) to an internet service provider 18 (ISP),which in turn preferably feeds the signal to a local router node 20 thatdirects the local signal to a relay system, e.g., the INTERNET cloud 22,which transmits the signal to a router 24 through a series of relays.The signal eventually arrives at an internet service provider 26 throughrouter 24.

[0023] As can be seen in FIG. 1, a plurality of destination sites 28,30, 32, 38, 40 and 42 are shown connected to internet service providers26 and 36 with each site being depicted in reference to a PC capable ofgenerating and transmitting e-mail messages, wherein each sitecorresponds to a specific telecommunications address. It is of course tobe appreciated that telecommunications system 10 includes a plurality ofrouters (e.g., routers 24 and 34 with each internet service providerbeing connected to a plurality of user sites (e.g., PC's 38, 40 and 42).

[0024] In accordance with the present invention, telecommunicationssystem 10 additional includes a messaging forwarding system 44, which aswill be further discussed below, enables e-mail messages to beautomatically forwarded to a forwarding address, which forwardingaddress is associated with a currently undeliverable e-mail address.Messaging forwarding system 44 preferably includes a PC 46 connected toan internet service provider 48, which PC 46 is provided with a uniquee-mail address (corrections@e-mailangel.com) and software programmed toperform the below described steps necessary to operate the presentinvention e-mail forwarding system 44. Internet service provider 48 ispreferably connected to INTERNET 22 via router 50.

[0025] As shown in FIG. 4, system 44 includes a software program thatincludes a lookup table 50, which is programmable by users to provide ane-mail forwarding address 52 associated with pre-programmed defunct(undeliverable) e-mail address[es] 54. It is to be appreciated thatusers of the present invention e-mail forwarding system 44 may accessand program the look-up table 50 of system 44 through any conventionalknown means, including via the internet 22 in which a user at PC site 28accesses the look-up table 50 in system 44, via the internet 22, viarouters 24 and 50, and internet service providers 26 and 48. Look-uptable 50 may include a plurality of defunct subscriber addresses (54+N),with each defunct address being associated with one or more forwardingaddresses (52+M).

[0026] It is to be appreciated that in this description of the presentinvention system 44, mention is made to both a “user” and “subscriber”of system 44. It is to be understood that a “user” of system 44 refersto anyone who is capable of transmitting an e-mail message and accessessystem 44 when it is desired to forward the message to a forwardingaddress, which forwarding address the sender is unaware of. A“subscriber” of system 44 refers to anyone who subscribes to the e-mailforwarding service of system 44 in which the subscriber registers both adefunct e-mail address 54 and at least one e-mail forwarding address 52with system 44. And of course e-mail forwarding system 44 is accessibleby any user.

[0027] In illustration, if a subscriber of system 44 closes an e-mailaccount (e.g., user@oldaccount.com) for what ever reason, the subscribermay however still desire to continue to receive messages sent to thataddress (e.g., user@oldaccount.com), but now wants to receive thosemessages at a different account (e.g., subscriber@newaccount.com). Inthe prior art, to accomplish this the subscriber had to resort toinforming everyone who had the old e-mail address (e.g.,user@oldaccount.com) of the new e-mail address (e.g.,subscriber@newaccount.com). In accordance with the present invention,the subscriber now merely accesses the subscriber's designated accountin system 44, via any known means such as the internet, registers thedefunct e-mail address (e.g., user@oldaccount.com) and associates itwith a desired forwarding e-mail address (e.g.,subscriber@newaccount.com). Thus when a sender of an e-mail desires totransmit a message to a subscriber of system 44 but only knows thesubscriber's old e-mail address (e.g., user@oldaccount.com), whichaccount is no longer active, the user now merely looks to system 44 toforward the message to an active account (e.g.,subscriber@newaccount.com), as will be discussed further below.

[0028] As indicated above, FIG. 1 is exemplary in nature, and thoseskilled in the art understand that equivalent substitutions of systemcomponents can be made. For example, electrical communications overconductive telephone lines, optical communications over optical fibers,radio communications, and microwave communications are substantiallyequivalent for purposes of the invention. Likewise, messages could berelayed through e-mail, facsimile, pager, PDA device or other capablecommunications system.

[0029] The method of use of system 44 will now be described withreference to FIGS. 2, 3 and 5 in conjunction with FIG. 1. Referring nowto FIG. 2, when an e-mail sender 14 desires to transmit a message to arecipient 30 having a known e-mail address (e.g., quine@luv-npi.com) ofthe recipient, the sender 14 transmits the e-mail message 500 (FIG. 5a)through conventional e-mail protocol, whereby the message is deliveredto the identified mail server 26 (e.g., luv-npi.com) of the recipient30, via the senders ISP server 18 (step 100). The recipient's 30 mailserver 26 then receives the e-mail message (step 102), and if the e-mailaccount is valid (e.g., quine@luv-npi.com) (step 104), the e-mailmessage is then accessible to the view and thus considered delivered(step 106). If the account is not a valid account (e.g.,quine@luv-npi.com) then the identified e-mail server 26 (e.g.,luv-npi.com) rejects the request (step 108) and sends a MAIL-DAEMONmessage 510 (FIG. 5b) to the sender's 14 e-mail server 18 indicatingthat the message is not deliverable (step 110). The sender's e-mailserver 18 then sends a message to the sender 14 that the attached e-mailmessage is undeliverable.

[0030] Since the sender 14 cannot contact the recipient (e.g., quine)via the now defunct e-mail address 54 (e.g., quine@luv-npi.com), thesender 14 is presented with the problem of how to contact the recipient.In order to overcome this problem, the present invention e-mailforwarding system 44 provides a solution by forwarding the e-mailmessage to a new address so long as the recipient 30 (e.g., quine)subscribes to the forwarding service of the system 44. In the currentillustrative example, the recipient (e.g., quine) registers the defuncte-mail address 54 (e.g., quine@luv-npi.com) with the system 44 andinstructs the system to forward all messages to a specified forwardinge-mail address 52 (e.g., quine@docsense.com), as depicted in the look-uptable of FIG. 4.

[0031] Returning now to the sender's 14 situation in which the sender 14still desires to transmit the e-mail message 500 but does not know thecorrect e-mail address. In accordance with the present invention, thesender 14 now forwards the entire message 510 that was previously sentto the intended recipient's defunct e-mail address (e.g.,quine@luv-npi.com), and rejected, to the e-mail address (e.g.,corrections@e-mailangel.com) assigned to the e-mail forwarding system 44(step 200). The e-mail server 48 (e.g., e-mailangel.com) that receivedthe message then informs the forwarding system 44 of the receipt of thismessage and afterwards the forwarding system 44 receives the messagefrom the e-mail server 48 (step 202). The forwarding system 44 thenparses message 510 and extracts the intended address for the recipient(e.g., quine@luv-npi.com) from the message (step 204). The forwardingservice 44 then does a look-up in table 50 for the intended address(e.g., quine@luv-npi.com) to determine if this address has beenregistered by a subscriber in the forwarding system 44 (step 206). Ifno, system 44 sends an e-mail message back to the sender 14 informingthe sender 14 that the defunct address of the recipient 30 (e.g.,quine@luv-npi.com) is not registered with the forwarding system 44 (step208). If yes, forwarding system 44, sends the e-mail message 510addressed to the recipients defunct address 54 (e.g., quine@luv-npi.com)to the recipient subscriber's new e-mail address 52 (e.g.,quine@docsense.com) as prescribed in the look-up table 50 of theforwarding system 44. Preferably, forwarding system 44 then sends ane-mail to the sender 14 indicating that the message original addressedto a defunct e-mail address has now been properly forwarded.

[0032] Thus, a clear advantage of the present invention e-mailforwarding system 44 is that a sender merely forward a rejected e-mailmessage to the e-mail address (e.g., corrections@e-mailangel.com)associated with the forwarding system 44 to determine if the previouslyrejected message can be forwarded to a proper e-mail address. And if itcan, the forwarding system automatically forwards the message to ane-mail address as prescribed by the recipient. Thus, a user of systemmerely has to forward a rejected e-mail message to forwarding system 44to utilize its forwarding services. Therefore, no internet access isrequired, only access to an e-mail server is required which is quiteadvantageous since many e-mail users only have access to an e-mailserver and not an internet server, such as staff employees incorporations and home users who utilize free, or inexpensive e-mailservices. Furthermore, in contrast to directory services, the systemdesign preserves recipient privacy by not providing the new e-mailaddress to the sender.

[0033] With reference now to FIG. 6, another embodiment of the presentinvention is depicted wherein there is shown messaging system 600 havingthe capabilities and operational features of the above-describedmessaging forwarding system 44 of FIGS. 1-5 but with the addedcapabilities of being able to correct or suggest a correct e-mailaddress. An example being the situation when a sender wants to send ane-mail to Doug Quine, and the senders knows that Doug Quine works atPitney Bowes and that he has an e-mail address at Pitney Bowes but doesnot know the precise e-mail address but nevertheless wants to send ane-mail to Doug Quine at Pitney Bowes. Thus the sender then goes aheadand transmits an e-mail to Doug Quine using an educated guess that DougQuine's e-mail address is Doug.Quine@pb.com (when it actually isquinedo@pb.com). In one embodiment described below, when the sendertransmits the e-mail to Doug.Quine@pb.com, the messaging forwardingsystem 600 is able to suggest sending the e-mail to quinedo@pb.com.

[0034] Preferably, the messaging system 600 operates within anenterprise (e.g., having a single computer or within an intranet) or mayoperate in the public domain where nonaffiliated users may utilize theinformation to improve address hygiene with the result being thatdigital document delivery success is enhanced. In essence, and asdescribed in further detail below, the present invention enables thesuccessful delivery of an e-mail to a person without knowing the personknowing the complete r correct e-mail address. In a first embodiment formessaging system 600 and illustrated in FIG. 6, messaging system 600 isto be understood to operate in the public domain with that of system 44shown in FIG. 1.

[0035] In reference to FIGS. 7a and 7 b, its method of operation willnow be described. First, when an e-mail sender 12 desires to transmit amessage to a recipient 40 having either what is thought as a knowne-mail address, or an educated guess of the recipient's e-mail address(e.g., Douglas.Quine@pb.com) as described above, the sender 12nevertheless transmits the e-mail message through conventional e-mailprotocol, whereby the message is delivered to the identified domain namemail server 36 (e.g., pb.com) specified in the recipient's e-mailaddress (e.g., Douglas.quine@pb.com), via the senders ISP server 18(step 600). The specified domain name mail server 36 then receives thee-mail message (step 602), and if the e-mail account is not recognizedby the domain name mail server 36 (e.g., Douglas.qine@pb.com) (step604), then the specified domain name mail server 36 rejects the requestand sends an undeliverable message (e.g., a MAIL-DAEMON message) back tothe sender 12, via the sender's e-mail server 18 indicating that themessage is not deliverable (step 610). As described above, the sender'se-mail server 18 then sends the message to the sender 12 that theattached e-mail message is undeliverable.

[0036] With continuing reference to FIG. 7a, since the sender 12 wasunsuccessful in delivering the e-mail message to the recipient, thesender then forwards the e-mail message to the messaging forwardingsystem 600 of the present invention (step 620). The messaging forwardingsystem 600 then receives the forwarded e-mail message (step 622), and asdescribed above, determines if a forwarding address has been registeredfor the undeliverable forwarded e-mail message (step 624). If yes, theabove described process of step 210 is then performed. If no, adetermination is then made as to whether the domain name address (e.g.,pb.com) of the undeliverable e-mail address (e.g. Douglas.quine@pb.com)has been registered with the messaging forwarding system 600 (step 626).If no, then messaging system 600 then preferably sends a message back tothe sender that it is unable to provide a forwarding e-mail address forthe undeliverable e-mail address (step 628 ).

[0037] If yes, and with reference now to FIG. 7b, a determination ismade as to whether an analysis to determine a “closet match” is to beperformed (step 650). As will be described further below, this “closetmatch” determination is essentially the performance of an analysis tofind the closet match to the username (e.g., douglas.quine) of theundeliverable e-mail in comparison to those usernames that arepre-registered with the messaging system 600 in association with thesubject domain name address (e.g., pb.com). Preferably, and as furtherdescribed below, when the administrator of the mail server 36 opens anaccount with the present invention messaging system 600, theadministrator decides whether to list all current usernames associatedwith the subject domain name address (e.g. pb.com) so as to enable theperformance of the closet match determination. If no “closest match”determination is to be performed (e.g., either the administrator of thesubject domain name address has decided not to list all associatedusernames, or has decided not to enable this feature in the messagingsystem) then the messaging system 600 preferably transmits an e-mailmessage back to the sender 12 indicating the format for usernamesfollowed for that domain name address (e.g., pb.com) (step 652). Anexample of such a message is:

[0038] THERE IS NO KNOWN E-MAIL ADDRESS FORDOUGLAS.QUINE@PB.COM—HOWEVER, THE FORMAT FOR USERNAMES RESIDING ATPB.COM IS TO USE THE FIRST SIX CHARATERS OF THE LAST NAME FOLLOWEDIMMEDIATLEY BY THE FIRST TWO CHARACTERS OF THE FIRST NAME—FOR EXAMPLE:MR. TOM WATSONER WOULD BE WASTONTO@PB.COM AND MS. ADELE ZON WOULD BEZONAD@PB.COM—TRY TO REFORMAT YOUR USERNAME IN ACCORDANCE WITH THISFORMAT AND RE-TRANSMIT YOUR E-MAIL MESSAGE—GOOD LUCK.

[0039] If yes, that is an analysis is to be performed for theundeliverable e-mail address (e.g., Douglas.quine@pb.com), then ananalysis of the username portion (e.g., Douglas.quine) of theundeliverable e-mail address (e.g., Douglas.quine@pb.com) is performedto determine a closet match (based upon prescribed criteria) to ausername(s) from all the usernames registered with the messaging system300 that are associated with the domain name (e.g., pb.com) of theundeliverable e-mail address (step 654). A determination is then made asto whether a closest match(es) has been made (step 656). If, no then theprocess goes to the above described step 652. If yes, then a message issent to the sender 12 indicating the closest match(es) that have beendetermined (step 658). An example of such a message is:

[0040] IT HAS BEEN DETERMINED THAT THE CLOSEST MATCH FORDOUGLAS.QUINE@PB.COM IS QUINEDO@PB.COM. IT IS SUGGESTED THAT THE E-MAILMESSAGE BE RE-SENT TO THIS E-MAIL ADDRESS.

[0041] When the sender 12 receives this e-mail message suggested theclosest match alternative e-mail address (e.g., quinedo@pb.com) (step660) the sender may then retransmit the once undeliverable e-mailmessage to the closest match e-mail address (step 662).

[0042] In summary, an e-mail forwarding system having a dedicated e-mailaddress for automatically forwarding e-mail has been described. Althoughthe present invention has been described with emphasis on particularembodiments, it should be understood that the figures are forillustration of the exemplary embodiment of the invention and should notbe taken as limitations or thought to be the only means of carrying outthe invention. Further, it is contemplated that many changes andmodifications may be made to the invention without departing from thescope and spirit of the invention as disclosed.
